18861-22-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 18861-22-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,8,6 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 18861-22:
(7*1)+(6*8)+(5*8)+(4*6)+(3*1)+(2*2)+(1*2)=128
128 % 10 = 8
So 18861-22-8 is a valid CAS Registry Number.

A simple photo-affinity labeling protocol
Li, Hong-Yu,Liu, Ying,Fang, Kan,Nakanishi, Koji
, p. 365 - 366 (1999)
After photo-crosslinking and proteolysis of a photoaffinity labeled ligand to its receptor, the ester group incorporated in the ligand is cleaved by an amine with specific functionality, which displaces the bulk of the ligand from the peptide fragments, a
